CREATE A CURVE USING THE STANDARD VARIANCE OF YIELD, ULTIMATE AND FAILURE STRESS¶
Generates engineering stress–strain variance curves by scaling a quasi-static base curve so that its yield, ultimate, and failure stress points span user-supplied min/max bounds. Use this worker when you need to produce a family of bounding stress–strain curves (e.g., for material scatter or design-of-experiments studies) from a set of dynamic and quasi-static coupon test curves.
When to use¶
Classification: process.
Tagged: bounding-curves, coupon, dynamic, engstress, failure, material-scatter, min-max, quasi-static.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Dynamic Eng Stress Strain Curves | dynamic_eng_stress_strain_curves | vector | — | Collection of dynamic engineering stress–strain curves (multiple vectors allowed) used as reference population for variance scaling; optional if only quasi-static data is available. | |
| Quasi-Static Eng Stress Strain Curve | quasi-static_eng_stress_strain_curve | vector | — | Single quasi-static engineering stress–strain curve that serves as the base curve whose key stress points are rescaled to the supplied min/max bounds. | |
| QS Yield Stress Min | qs_yield_stress_min | scalar | 0 | Minimum allowable quasi-static yield stress value (stress units consistent with the input curves, default 0); defines the lower bound of the yield stress scatter band. | |
| QS Yield Stress Max | qs_yield_stress_max | scalar | 0 | Maximum allowable quasi-static yield stress value (stress units consistent with the input curves, default 0); defines the upper bound of the yield stress scatter band. | |
| QS Ultimate Stress Min | qs_ultimate_stress_min | scalar | 0 | Minimum allowable quasi-static ultimate (peak) stress value (same stress units, default 0); sets the lower bound of the ultimate stress scatter band. | |
| QS Ultimate Stress Max | qs_ultimate_stress_max | scalar | 0 | Maximum allowable quasi-static ultimate (peak) stress value (same stress units, default 0); sets the upper bound of the ultimate stress scatter band. | |
| QS Elongation Strain Min | qs_elongation_strain_min | scalar | 0 | Minimum allowable quasi-static elongation (failure) strain value (dimensionless or %, default 0); sets the lower bound of the failure strain scatter band. | |
| QS Elongation Strain Max | qs_elongation_strain_max | scalar | 0 | Maximum allowable quasi-static elongation (failure) strain value (dimensionless or %, default 0); sets the upper bound of the failure strain scatter band. | |
| Elastic Modulus | elastic_modulus | scalar | 0 | ||
| Yield Offset | yield_offset | scalar | 0.002 | ||
| Levels to generate | levelstogenerate | scalar | 3 | ||
| Level Names | level_names | scalar | min,mean,max |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_engstress_variance_output_1 | curves_engstress_variance_output_1 | vector | Generated engineering stress–strain variance curve (or family of curves) whose yield, ultimate, and failure stress points are bounded by the supplied min/max limits, ready for downstream material card authoring or DOE studies. |
